Why some posts get just 1 point on Ask Expert responses?

Some of my responses under Ask Experts section get just 1 or zero points when submitted. What exactly does that indicate? Poor quality of post? I guess not, because I get 1 point or zero point on submitting the response, not after review. I just want to know the reason as I want to correct my mistakes if any.As an example , here is the link to one my responses- http://www.techulator.com/experts/3389-I-would-like-to-know-the-features-of-a-recently-released-smartphone-One-Plus-One.aspx
